Steven, Before I tackle this problem, I would like to try something. The LDM host idd.cise-nsf.gov no longer exists, so would you please replace that hostname with host idd.meteo.psu.edu in all REQUEST-s for data. Then, restart your LDM and let me know if the problem persists or not. > *Tom or any other Unidata support person,* > > *Our machine is named blizzard.oswego.edu with a CNAME of > met-020157.oswego.edu.* > > ============================================================== > #dig blizzard.oswego.edu > > ; <<>> DiG 9.8.2rc1-RedHat-9.8.2-0.17.rc1.el6_4.4 <<>> blizzard.oswego.edu > ;; global options: +cmd > ;; Got answer: > ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 38877 > ;; flags: qr aa rd ra; QUERY: 1, ANSWER: 2, AUTHORITY: 2, ADDITIONAL: 2 > > ;; QUESTION SECTION: > ;blizzard.oswego.edu.
